So I have done a fresh install with Sabayon_Linux_DAILY_amd64_K.iso Built on: 2012-02-05 02:06:23.761878 on the same box as in my first reply and was just about report that I was having no problems(uptime 3:34) until I inserted a usb stick and the Plasma Desktop shell -The KDE Crash Handler window appeared saying it closed unexpectedly DetailsExecutable: kdeinit4 PID: 7960 Signal: Segmentation fault (11)

The Developer tab had no info displayed but had a suggestion to install gdb and press the reload button, guess I was just lucky that all the programs (one being konsole) that I had open before the crash were still visible on the black screen so I pressed the reload button after I installed sys-devel:gdb-7.3.1-r1~0.tbz2, which then showed

Sorry I did not make it clear enough that I loaded limbo repo and installed kde 4.8

Idea of the post, to let others know that yes I am having the crashes with kde 4.8 installed via limbo on a fresh installBut according to my dmesg I do have other problems that I should look at and try fix Note because this was only a test install I will not be looking in to the errors and warnings unless they also appear in in the other system (the one from first reply)

Also, joost, I issued the command you recommended and here's the output. It appears as though 'raster' is set correctly. I also disabled Compiz before updating so I'm certain that's not the culprit. Any other ideas? The backtrace is Greek to me... Thanks for any help!

Okay, since yesterday, I have updated to the latest nvidia drivers... plasma-shell still crashesI've disabled all visual effects...plasma-shell still crashesI've successfully run equo deptest && equo libtest as root user, then rebooted after a few packages were istalled...plasma-shell still crashes

Personally, my instinct tells me the crashes are due to my two permanantly connected USB erxternal hard disks but I have no evidence to support this theory other than crashes appear to occur whenever there's disk activity on those drives. Also, when I insert a flash drive and then browse the contents, plasma-desktop will crash so frequently I can't keep up with them and I wind up with a permanant black screen.

In short, my system is not useable with KDE 4.8.0 and my opinion of it so far is that it's a piece of buggy crap! At least on my modern, perfectly standard desktop system. I'm returning to KDE 4.7.4 and sticking with that until possibly KDE 4.8.1, even if that means I disable magneto and avoid updates for a few months.

With my system the one that I did the fresh install with the crashes occur when I select safely remove a usb device (4gig stick) from device notifier or dolphin but yet on the other original install the crash occurs when inserting an 8 gig usb stick, so there are some bugs but my system is working with kde 4.8 and now after some more updates from limbo the original install returns to nominal (no black screen) after a crash

If you still want to use limbo repo I recommend that you create another partition on one of your hard drives so that when problems occur with limbo packages you won't have go back to standard repo and reinstall older packages

Thanks for the corroborating information. I have always, fore the most part, used the Limbo repository because I like living on the cutting edge. I've had my original system since 5.o without any major issues (none that I couldn't find a fast resolution to.) However, there are certain bugs I can't live with; a constantly crashing desktop being one of them. I'm happy to hear that some updates in Limbo have resolved the problem for you. Just the same, I think I'm going to wait a bit longer before re-enabling the Limbo repository. The fact of the matter is that KDE 4.7.4 is quite stable now and KDE 4.8 doesn't have any new features that I can't live without for a few weeks! If you shoudl learn any more about this alleged USB bug, please post it! Thanks again for your help!

No worries Joost! Everyone's computer is a little different. Mine's just acting like a spoiled child! All I know is KDE 4.7.x works absolutely perfectly; it's only KDE 4.8 that crashes. Something is obviously different!!! The question is, what?!? I'm planning on doing another upgrade attempt this weekend. I'll do whatever I can to pinpoint this issue of mine (e.g., boot with and without USB devices attached; fresh profile, etc.) Thanks again for your help! (I still think Sabayon is the BEST distro ever!!)
